Subject: Add browser-style project tabs: persistent home + one tab per project

The project list is now a persistent home tab; each opened project runs
in its own WebContentsView tab below a 38px tab strip (hidden when only
home is open). Background tabs stay fully live (sync, collab, terminals).

Main process: per-project singletons (socket, sync bridge, compilation
manager, MCP state, compile watcher) become per-tab ProjectSession
objects keyed by webContents.id; PTYs are scoped per webContents.
Hardened against races found in review: concurrent ot:connect dedupe,
teardown/reopen serialization on the shared sync dir, destroyed-window
guards on all bridge sends, real logout that closes project tabs.

Renderer: tabs strip in the home renderer (wt-* classes, distinct from
the editor's .tab-bar file tabs), project tabs boot from ?projectId= and
connect straight into the editor; Back closes the tab.
